用于乳腺切除手术的磁悬吊牵拉系统的研制

Development of Magnetic Suspension Traction System for Adenomammectomy

针对当前乳腺切除手术中存在的暴露牵拉相关瓶颈问题,结合磁定位牵拉技术的优势特点,该文介绍了一种用于乳腺切除手术的磁悬吊牵拉系统。该系统包括体外支架、磁悬吊单元、磁牵拉单元与内磁体构成。其中体外支架与手术床相结合,实现整个系统的定位;磁悬吊单元与内磁体相配合,实现深部皮肤的牵拉,辅助深部组织的暴露;磁牵拉单元可进行切缘牵拉。在不延长切口长度情况下,与传统术式下需要3名术者进行皮瓣游离相比,磁悬吊牵拉系统辅助下仅需1术者,且皮瓣游离时间短(462.00 s vs. 609.35 s)、术者受干扰次数少(1.83次vs. 5.5次)。因此该系统不仅能够降低乳腺切除手术的操作难度,还可实现小切口、隐蔽切口的乳腺切除术,并能够减少术中人员,甚至实现单人操作,对于促进乳腺切除手术的进步具有重大意义。

Regarding the bottlenecks related to exposure and traction in current adenomammectomy, we introduced a magnetic suspension traction system for adenomammectomy based on the advantages of magnetic positioning traction technique. The system comprised an external stent, a magnetic suspension unit, a magnetic traction unit and an inner magnet. The external stent was combined with the operating bed to realize the positioning of the whole system. The magnetic suspension unit cooperated with the inner magnet to realize deep skin traction and assist the exposure of the deep tissue. The magnetic traction unit could perform the cutting edge traction. Compared with the traditional method, which required 3 surgeons to perform flap dissociation, the magnetic suspension traction system only needed 1 surgeon, with similar incision length, shorter flap dissociation time(462.00 s vs. 609.35 s) and less interference(1.83 vs. 5.5). The system not only can reduce the difficulty of adenomammectomy, but also can achieve small and concealed incision in adenomammectomy. The system also reduces intraoperative personnel, and even achieves single operation, which is of great significance for promoting the progress of adenomammectomy.
